Correction Commissioner Dora Schriro released a statement Monday night saying the department was “shocked and saddened” by the events.

“Each of us takes an oath of office to preserve and protect the lives of others,” Schriro said in the statement. “This is an unspeakable tragedy.”

Officer Kevin Ambrose was responding to a 911 call Monday at an apartment complex in Springfield from 29-year-old Charlene Mitchell who said her ex-boyfriend was nearby and she feared for her life.

The ex-boyfriend, 35-year-old Shawn Bryan, was a correction officer assigned to Rikers Island.

When Ambrose arrived, Bryan and the woman were in a parking lot, police said. They three went to Mitchell’s apartment, where Bryan pushed Mitchell inside, followed her and slammed the door on Ambrose, who tried to get inside, according to police.

Bryan then fired through the door, opened it and fired at Ambrose again killing the officer, police said. He then shot and critically wounded his ex-girlfriend before killing himself.

Ambrose and Bryan were pronounced dead at Baystate Medical Center and Mitchell was in critical condition there late Monday after undergoing surgery.

Mitchell had obtained the restraining order, to be served on Bryan, about 45 minutes before the shootings, according to police.
